- 2009, RPS built their micronizing plant after discovering an agricultural market need for toll ultrafine grinding of various organic and mineral based inputs for use in liquid soil amendments.
- 2014, RPS branched out and focused on expanding their agromineral portfolio to include Canadian Wollastonite and exploring for new market opportunities
- 2015 established new markets and built a larger grinding mill to be able to service these pulverized markets
- 2016 purchased a new location to accommodate the growing markets.
- 2017 Built two pelleting lines and started marketing VolcanoPhos to the general public.
- 2018 Arie joined RPS as a fulltime partner in the business.

Peter Van Straaten M.Sc., Ph.D. in geology (University of Goettingen, Germany)
Professor Emeritus at University of Guelph
Peter's research is concentrated in two areas, agrogeology and environmental geology. The agrogeological research and development is on the use of locally available minerals and rocks to enhance soil productivity. Currently Peter has collaborative research projects in modification and utilization of phosphate rocks and rock fertilizers underway in Kenya, Uganda, Tanzania and Zambia as well as in Brazil and Indonesia.The main initiative of these research projects is to develop appropriate and economic techniques to enhance nutrient release from minerals and rocks. Research in environmental geology focuses on health-related geochemistry and industrial mineral (phosphates, zeolites, vermiculites, etc) and organic 'wastes' as potential 'resources'.
